4. f(x,y) is homogeneous of degree 2.

5. a) f(x,y) is homothetic with h(x,y) = xy and g(x) = x-1

4. Show that f(x,y)=[tex]x^2[/tex]y is homogeneous, and find its degree of homogeneity:

A function is said to be homogeneous of degree k, if it satisfies the condition:

f(tx,ty) = [tex]t^k[/tex]f(x,y)

We have f(x,y) = [tex]x^2[/tex]y. Let’s check if it satisfies the above condition:

f(tx,ty) = [tex](tx)^2(ty) = t^3x^2y = t^2(x^2y[/tex]) = [tex]t^2[/tex]f(x,y)

Hence f(x,y) is homogeneous of degree 2.

5. Which of the following functions f(x,y) are homothetic? Explain.

(a) f(x,y)=[tex](xy)^2[/tex]+1

(b) f(x,y)=[tex]x^2+y^3[/tex]

Let us first understand the meaning of homothetic transformation.

A homothetic transformation is a non-rigid transformation of the Euclidean plane that preserves the direction of the straight lines but not their length. It stretches or shrinks the plane by a constant factor called the dilation.

Let’s now find out whether the given functions are homothetic or not.

(a) f(x,y)=[tex](xy)^2[/tex]+1

In order to check if f(x,y) is homothetic or not, we need to check if the function satisfies the following condition:

f(x,y) = g(h(x,y))

where g is a strictly monotonic function and h is a homogeneous function with degree 1

We have

f(x,y) = [tex](xy)^2[/tex]+1

Let’s assume g(x) = x - 1, then g(x+1) = x

Similarly, let’s assume h(x,y) = (xy), then h(tx,ty) = [tex]t^2[/tex]h(x,y)

Now, we have

g(h(x,y)) = h(x,y) - 1 = (xy) - 1

Thus f(x,y) is homothetic with h(x,y) = xy and g(x) = x-1

(b) f(x,y)=[tex]x^2+y^3[/tex]

We can’t write this function in the form f(x,y) = g(h(x,y)) where h(x,y) is a homogeneous function with degree 1. Hence this function is not homothetic.

The equation z = 2y² - 1 represents a quadratic function in three-dimensional space. The correct symmetry for the equation z = 2y² - 1 is symmetric about the y-axis.

To analyze the symmetry of the equation z = 2y² - 1, we can substitute (-y) for y and observe if the equation remains unchanged. Substituting (-y) for y, we get z = 2(-y)² - 1, which simplifies to z = 2y² - 1.

Since the equation remains the same after substituting (-y) for y, the equation is symmetric about the y-axis. This means that if we reflect the graph of the equation across the y-axis, the resulting graph will be identical to the original.

The combinatorial proof states that [("+¹), n odd 2" = + (^ † ¹ ) + (^² + ¹) + [G‡D, n even for n ≥ 1.

To provide a combinatorial proof for the statement:

For n ≥ 1, [("+¹), n odd 2" = + (^ † ¹ ) + (^² + ¹) + ··· + + [G‡D, n even.

Let's define the following:

[("+¹), n odd 2" represents the number of subsets of a set with n elements, where the number of elements chosen is odd.

(^ † ¹ ) represents the number of subsets of a set with n elements, where the number of elements chosen is odd and contains the first element of the set.

(^² + ¹) represents the number of subsets of a set with n elements, where the number of elements chosen is odd and does not contain the first element of the set.

[G‡D, n even represents the number of subsets of a set with n elements, where the number of elements chosen is even.

Now, let's prove the statement using combinatorial reasoning:

Consider a set with n elements. We want to count the number of subsets that have an odd number of elements and those that have an even number of elements.

When n is odd, we can divide the subsets into two categories: those that contain the first element and those that do not.

[("+¹), n odd 2" represents the number of subsets of a set with n elements, where the number of elements chosen is odd.

(^ † ¹ ) represents the number of subsets of a set with n elements, where the number of elements chosen is odd and contains the first element of the set.

(^² + ¹) represents the number of subsets of a set with n elements, where the number of elements chosen is odd and does not contain the first element of the set.

Therefore, [("+¹), n odd 2" = + (^ † ¹ ) + (^² + ¹) since every subset of an odd-sized set either contains the first element or does not contain the first element.

When n is even, we can divide the subsets into those with an odd number of elements and those with an even number of elements.

[G‡D, n even represents the number of subsets of a set with n elements, where the number of elements chosen is even.

Therefore, [("+¹), n odd 2" = + (^ † ¹ ) + (^² + ¹) + [G‡D, n even since every subset of an even-sized set either has an odd number of elements or an even number of elements.

Hence, the combinatorial proof shows that [("+¹), n odd 2" = + (^ † ¹ ) + (^² + ¹) + [G‡D, n even for n ≥ 1.

The solution to the system of linear inequalities y >= x + 1 and y < 3x - 2 is the shaded region between the two boundary lines, excluding the line y = 3x - 2 itself.

To graph the solution to the system of linear inequalities y >= x + 1 and y < 3x - 2, we will plot the boundary lines and shade the appropriate regions.

First, let's graph the boundary line for y = x + 1. To do this, we plot the points (0, 1) and (1, 2) and draw a straight line passing through these points. This line represents the equation y = x + 1.

Next, let's graph the boundary line for y = 3x - 2. We plot the points (0, -2) and (1, 1) and draw a straight line through these points. This line represents the equation y = 3x - 2.

Now, let's determine the shading for each inequality.

For the inequality y >= x + 1, we shade the region above the line y = x + 1. This means all points that lie above or on the line are part of the solution.

For the inequality y < 3x - 2, we shade the region below the line y = 3x - 2. This means all points that lie below the line are part of the solution, but the points on the line itself are not included.

The solution to the system of linear inequalities is the region that satisfies both inequalities simultaneously, which is the shaded area that lies above the line y = x + 1 and below the line y = 3x - 2.

The values of A and B about velocity and acceleration are A = -1/5 and B = 5.5.

We know that acceleration (a) is the rate of change of velocity (v) with respect to time (t), expressed as a derivative: a = dv/dt.

Let's denote the velocity as v and the acceleration as a.

We are given two data points:

1) When the velocity is 20 meters per second, the acceleration is 1.5 meters per second squared: v = 20, a = 1.5.

2) When the velocity is 15 meters per second, the acceleration is 2.5 meters per second squared: v = 15, a = 2.5.

To find A and B, we can set up two equations based on the given data points:

1.5 = A * 20 + B

2.5 = A * 15 + B

Simplifying these equations, we have:

20A + B = 1.5

15A + B = 2.5

We can solve this system of linear equations to find the values of A and B.

Subtracting the second equation from the first equation, we get:

(20A + B) - (15A + B) = 1.5 - 2.5

5A = -1

Dividing both sides by 5, we find:

A = -1/5

Substituting this value of A into either of the equations, we can solve for B:

15 * (-1/5) + B = 2.5

-3 + B = 2.5

B = 2.5 + 3

B = 5.5

Therefore, the values of A and B are A = -1/5 and B = 5.5.

The maximum value of f over S is approximately 13.6569 and the minimum value of f over S is approximately -10.6569.

Let f(x, y) = 4x − 3y +2 and S = {(x, y): 2x² + 3y² ≤ 1}. Find the maximum and minimum values of f over the region S. In order to find the maximum and minimum values of f over the region S, we need to use Lagrange multipliers. We need to maximize/minimize f(x,y) subject to the constraint g(x,y) = 2x² + 3y² − 1 = 0, i.e., we need to find the critical points of the function f(x,y) + λg(x,y), where λ is the Lagrange multiplier.So, we have to find the partial derivatives of f(x, y) and g(x, y) and set up the following system of equations:
f'x(x,y) + λg'x(x,y) = 0
f'y(x,y) + λg'y(x,y) = 0
g(x,y) = 0
We have:
f'x(x,y) = 4
f'y(x,y) = -3
g'x(x,y) = 4x
g'y(x,y) = 6y
Solving the above system of equations, we get:
4 + 4λx = 0 …(1)
-3 + 6λy = 0 …(2)
2x² + 3y² -1 = 0 …(3)
From equations (1) and (2), we get:
λ = -1 / (4x)
λ = 1 / (2y)
Equating both, we get:
x = -2y …(4)
Substituting equation (4) in equation (3), we get:
2(4y²) + 3y² = 1
y² = 1 / 2
y = ±1 / √2
Substituting the value of y in equation (4), we get:
x = -2y = -2(±1 / √2) = ±√2
So, the critical points are:
(√2, -1 / √2) and (-√2, 1 / √2)
Now, we need to find the value of f at these critical points. We have:
f(√2, -1 / √2) = 4(√2) - 3(-1 / √2) + 2 = 8√2 + 3 / √2 + 2
f(-√2, 1 / √2) = 4(-√2) - 3(1 / √2) + 2 = -8√2 + 3 / √2 + 2
Also, we need to check the value of f(x,y) on the boundary of S. We have:
g(x,y) = 2x² + 3y² -1 = 0
Simplifying, we get:
3y² = 1 - 2x²
y = ±√((1 - 2x²) / 3)
Now, we need to find the value of f(x,y) on the boundary of S, i.e., for y = √((1 - 2x²) / 3) and y = -√((1 - 2x²) / 3). We have:
f(x,√((1 - 2x²) / 3)) = 4x − 3√((1 - 2x²) / 3) +2
f(x,-√((1 - 2x²) / 3)) = 4x + 3√((1 - 2x²) / 3) +2
To find the maximum and minimum values of f over S, we need to find the maximum and minimum values of f at the critical points and at the points on the boundary of S that we have just found. Therefore, we have:
f(√2, -1 / √2) = 8√2 + 3 / √2 + 2 ≈ 13.6569
f(-√2, 1 / √2) = -8√2 + 3 / √2 + 2 ≈ -10.6569
f(1 / √2, √(1 / 6)) = 4 / √2 - 3(√(1 / 6)) + 2 ≈ 0.5894
f(-1 / √2, -√(1 / 6)) = -4 / √2 - 3(√(1 / 6)) + 2 ≈ -9.5894
Therefore, the maximum value of f over S is approximately 13.6569 and the minimum value of f over S is approximately -10.6569.

(a) Mishu will receive $51,975 after one year if he invests at a rate of 3.95%.

(b) Mishu will receive approximately $46,729.77 after one year if he invests for six months at a time at a rate of 3.85% each time.

(c) The one-year rate would have to be approximately 26.155% to yield the same amount of interest as the investment described in part (b).

(a) How much will Mishu receive after one year if he invests at a rate of 3.95%?

To calculate the amount Mishu will receive after one year, we can use the formula for compound interest:

Amount = Principal × [tex](1+Rate/100)^{Time}[/tex]

Where:

Principal = $50,000 (initial investment)

Rate = 3.95% = 0.0395 (converted to decimal)

Time = 1 year

Plugging in the values into the formula:

Amount = $50,000× (1 + 0.0395)¹

Amount = $50,000 × (1.0395)

Amount = $51,975

Therefore, Mishu will receive $51,975 after one year if he invests at a rate of 3.95%.

(b) How much will Mishu receive after one year if he invests for six months at a time at a rate of 3.85% each time?

Since Mishu is investing for six months at a time, we need to calculate the compound interest twice (for two six-month periods).

First, let's calculate the amount after the first six months:

Amount1 = Principal ×[tex](1+Rate/100)^{Time}[/tex]

Amount1 = $45,000 × [tex](1+0.0385)^{0.5}[/tex]

Amount1 = $45,000 ×[tex](1.0385)^{0.5}[/tex]

Amount1 = $45,000 × (1.0192)

Amount1 = $45,864

Now, let's calculate the amount after the second six months:

Amount2 = Amount1 × [tex](1+Rate/100)^{Time}[/tex]

Amount2 = $45,864 × [tex](1+0.0385)^{0.5}[/tex]

Amount2 = $45,864 × [tex](1.0385)^{0.5}[/tex]

Amount2 = $45,864 × (1.0192)

Amount2 = $46,729.77

Therefore, Mishu will receive approximately $46,729.77 after one year if he invests for six months at a time at a rate of 3.85% each time.

(c) What would the one-year rate have to be to yield the same amount of interest as the investment described in part (b)?

To find the one-year rate that would yield the same amount of interest, we can set up an equation using the formula for compound interest.

Let's assume the one-year rate we're looking for is "x%".

Using the same initial principal ($45,000), the equation becomes:

$45,000 ×(1 + x/100) = $46,729.77

Simplifying the equation:

1 + x/100 = $46,729.77 / $45,000

1 + x/100 = 1.26155

Subtracting 1 from both sides:

x/100 = 0.26155

Multiplying both sides by 100:

x = 26.155

Therefore, the one-year rate would have to be approximately 26.155% to yield the same amount of interest as the investment described in part (b).

A complete measure space consists of a set X, a sigma-algebra E of subsets of X, and a measure μ defined on E. Given a complete measure space (X, E, μ) and functions f and g defined on E, if f and g are equal almost everywhere (a.e.) and f is measurable on E, then g is also measurable on E.

A measure space is considered complete if it contains all subsets of sets with measure zero. It consists of a set X, a sigma-algebra E (a collection of subsets of X), and a measure μ that assigns non-negative values to sets in E, satisfying certain properties.

Now, let (X, E, μ) be a complete measure space and E € E. We are given two functions, f: E → [0, ∞) and g: E → [-∞, ∞], such that f = g almost everywhere (a.e.). This means that the set of points where f and g differ is of measure zero.

To prove that g is measurable on E, we need to show that for any Borel set B in the extended real line, g^(-1)(B) = {x ∈ E: g(x) ∈ B} belongs to the sigma-algebra E.

Since f = g a.e., the sets {x ∈ E: f(x) ∈ B} and {x ∈ E: g(x) ∈ B} are essentially the same, differing only on a set of measure zero. As f is measurable on E, the set {x ∈ E: f(x) ∈ B} belongs to E. Since E is a sigma-algebra, it is closed under taking complements and countable unions.

Thus, g^(-1)(B) = {x ∈ E: g(x) ∈ B} can be expressed as the union of two sets, one belonging to E and the other being a subset of a set of measure zero. As a result, g^(-1)(B) also belongs to E, proving that g is measurable on E.

In conclusion, if two functions f and g are equal almost everywhere and f is measurable on a complete measure space, then g is also measurable on that space.

The given differential equation is a non homogeneous linear second-order equation with variable coefficients. To find the particular solution, we assume it has the same form as the nonhomogeneous terms in the equation. In this case, the nonhomogeneous terms are 2x^4, x^2e^(-3x), and sin(x).

By substituting these assumed forms into the differential equation and solving for the coefficients, we can find the particular solution.

A) The amplitude is 0.129 m.

B) The position at t = 0 is also 0.129 m.

C) The velocity at t = 0 is approximately -0.913 m/s.

A) To find the amplitude of a simple harmonic oscillator, we need to know the maximum displacement from the equilibrium position. In this case, the amplitude (A) can be determined using the position (x) at any given time. The amplitude is equal to the absolute value of the maximum displacement.

Given that the position of the block at t = 1 s is x = 0.129 m, we can find the amplitude as follows:

Amplitude (A) = |x| = |0.129 m| = 0.129 m

Therefore, the amplitude of the oscillator is 0.129 m.

B) To find the position at t = 0, we need to consider the motion of the oscillator in terms of its phase. The position of the block at any given time can be expressed as:

x(t) = A * cos(ωt + φ)

where x(t) is the position at time t, A is the amplitude, ω is the angular frequency, t is the time, and φ is the phase constant.

At t = 0, the position x(t) will be at its maximum, which is equal to the amplitude A. Therefore, the position at t = 0 is equal to the amplitude:

Position at t = 0 = A = 0.129 m

C) To find the velocity at t = 0, we can differentiate the position function with respect to time:

v(t) = -A * ω * sin(ωt + φ)

At t = 0, the velocity v(t) can be calculated as:

Velocity at t = 0 = v(0) = -A * ω * sin(φ)

Since sin(φ) can vary between -1 and 1, the magnitude of sin(φ) is at most 1. Therefore, the maximum value of the velocity occurs when sin(φ) = 1.

Velocity at t = 0 = -A * ω * 1

Now, let's calculate the velocity using the given values:

Mass (m) = 2 kg

Spring constant (k) = 100 N/m

The angular frequency (ω) can be calculated using the formula ω = √(k/m), where ω is in radians per second:

ω = √(k/m) = √(100 N/m / 2 kg) = √(50 rad/s) ≈ 7.071 rad/s

Using this value, we can calculate the velocity at t = 0:

Velocity at t = 0 = -A * ω * 1 = -0.129 m * 7.071 rad/s * 1 = -0.913 m/s

Therefore, the velocity at t = 0 is approximately -0.913 m/s.

The multiplication yields (x³ - x² + 2x² - 2x + 2x - 2). Now we can simplify the expression and obtain (x³ + x² - 2x + 2) dx. We can apply the power rule of integration to the integrand. The power rule states that if we integrate xⁿ, the result is (xⁿ+1)/(n+1) + C where C is a constant of integration.

Therefore, applying the power rule of integration to the integrand (x³ + x² - 2x + 2) yields:(x⁴/4) + (x³/3) - (2x²/2) + (2x) + C.This is the antiderivative of (x²+2x+2) (x−1). It is essential to include the constant of integration because it represents an infinite number of antiderivatives that differ by a constant value.

Therefore, the complete solution is (x⁴/4) + (x³/3) - x² + (2x) + C, where C is a constant that represents the constant of integration.

To obtain the antiderivative of a function, we can use integration rules. The power rule is one of the most common integration rules that we can use to integrate a function. We can use the power rule to find the antiderivative of (x²+2x+2) (x−1), which is (x⁴/4) + (x³/3) - x² + (2x) + C. The constant of integration is essential to include in the solution because it represents an infinite number of antiderivatives that differ by a constant value.

In this question, the correct choice is C. The matrix cannot be diagonalized because it does not have a sufficient number of linearly independent eigenvectors.

To determine if a matrix can be diagonalized, we need to check if it has a sufficient number of linearly independent eigenvectors. In this case, the matrix has real eigenvalues 2 and 7. We need to find the corresponding eigenvectors for these eigenvalues and check if they are linearly independent.

Using the eigenvalue 2, we solve the equation (A - 2I)x = 0, where A is the given matrix and I is the identity matrix. The resulting system of equations is:

-1x + 2y - 4z = 0

x - 2y + 6z = 0

Solving this system, we find that the solutions are of the form x = 2y - 4z and y, z are free variables. This means that we have infinitely many solutions and no unique eigenvector corresponding to the eigenvalue 2.

Similarly, using the eigenvalue 7, we solve the equation (A - 7I)x = 0 and find that we have infinitely many solutions and no unique eigenvector corresponding to the eigenvalue 7.

Since we don't have a sufficient number of linearly independent eigenvectors, the matrix cannot be diagonalized.

The estimated local maximums are (0,-2) and (0,π), and the estimated local minimums are (0,0) and (0,2π).

The graph of f consists of two parts: a line increasing to (0,-2) and a curve starting at (0,0) and intercepting the x-axis at (0, π, and 2π). To estimate the local maximum and local minimum of the graph, we need to look for points where the function changes direction.For the line segment, the graph is increasing until it reaches (0,-2). This point can be considered a local maximum because the graph starts decreasing afterward.

For the curve, we have points at (0,0), (0, π), and (0, 2π). At (0,0), the graph is flat and does not change direction, so it is considered a local minimum.

At (0,π), the graph changes direction from increasing to decreasing, making it a local maximum.Similarly, at (0, 2π), the graph changes direction from decreasing to increasing, which means it is also a local minimum.Therefore, the estimated local maximums are (0,-2) and (0,π), and the estimated local minimums are (0,0) and (0,2π).

Answer:

OK = 6/2 = 3√2

Step-by-step explanation:

Since JKLM is a rectangle inscribed in circle O, its diagonals JL and KM are diameters of the circle. Therefore, the center of the circle, O, is the midpoint of JL and KM. Let N be the midpoint of JK, so JL and KM pass through N.

Since JKLM is a rectangle, we have JK=ML=6 and KL=JM=14. Let x be the length of OM.

Then, ON is the midpoint of JL, so JL=2ON. Similarly, KM=2OM.

Since JL+KM=18 (the diameter of the circle), we have:

2ON + 2OM = 18

Simplifying this equation, we get:

ON + OM = 9

Since ON=NM=6/2=3 and JK=6, we have JN = sqrt(JK^2 - MN^2) = sqrt(6^2 - 3^2) = sqrt(27).

Then using the Pythagorean theorem, we find:

OM^2 = ON^2 + NM^2

OM^2 = 3^2 + (sqrt(27))^2

OM^2 = 9 + 27

OM^2 = 36

OM = 6

Therefore, the length of OK, which is half of OM, is:

OK = 6/2 = 3√2

So, OK in simplest radical form is 3√2.

The scale factor of the transformation from the original square to the new square is 0.0833.

The scale factor is defined as the ratio of any two corresponding sides in two similar geometric figures. When given a square with a side length of 42 meters and a square with a side length of 3.5 meters, and we want to determine the scale factor of the transformation, we need to apply the formula for scale factor which is: SF= AB/ A′B′ Where SF is the scale factor, AB represents the corresponding side in the original square and A'B' represents the corresponding side in the new square.

From the question, the original square has a side length of 3.5 meters, while the new square has a side length of 42 meters.

Let us now substitute the values into the formula. SF= AB/ A′B′SF= 3.5/42SF= 0.0833Therefore, the scale factor of the transformation from the original square to the new square is 0.0833.

The integral ∫(√(36 - x²))/(7 - 2x) dx can be rewritten as ∫(f(u)) du, where u = 3 - 2x, a = 3 and f(u) = (√(36 - (9 - u)²))/(7 - (3 - u)).

To rewrite the integral using the substitution u = 3 - 2x, we need to express dx in terms of du. Solving for x in terms of u, we get x = (3 - u)/2. Taking the derivative with respect to u, we have dx = -1/2 du.

Substituting x and dx in the integral, we get ∫(√(36 - ((3 - u)/2)²))/(7 - 2((3 - u)/2)) (-1/2) du.

Simplifying further, we have ∫(√(36 - (9 - u)²))/(7 - (3 - u)) (-1/2) du.

The resulting integral can be written as ∫(f(u)) du, where f(u) = (√(36 - (9 - u)²))/(7 - (3 - u)). The limits of integration remain the same.

Both Sean and Candice are incorrect in their statements because adding any number to –100 will result in a different number.

This is because –100 is a fixed number that cannot be changed by simply adding any number to it. To add a number to –100 and still have –100 means that the number being added is zero. This is because adding zero to any number does not change the value of that number.

So, Sean’s statement is partially correct because the only number that can be added to –100 without changing its value is zero.On the other hand, Candice’s statement is also incorrect because adding two numbers to –100 will result in a different number. This is because –100 is a fixed number and the sum of any two numbers added to it will give a different value.

To illustrate this, consider the addition of two numbers, say a and b, to –100:

–100 + a + b= (–100 + a) + b= (a – 100) + b= a + (b – 100)

Therefore, adding two numbers to –100 does not result in –100, but in a new number that depends on the values of a and b.

Hence, Candice’s statement is incorrect.In conclusion, neither Sean nor Candice is correct in their statements. Adding any number to –100 will result in a different number, except for the number zero.

Therefore, Sean’s statement is partially correct. Candice’s statement, on the other hand, is incorrect because adding any two numbers to –100 will result in a different value.

The values of `sin x`, `cos x` are `10/√101` and `1/√101` respectively.

Given that `tan x = 10` and `x` lies in the interval `[0, π/2]`.

We need to find the values of `sin x` and `cos x`.

Let's try to use the identities of `tan x`, `sin x`, and `cos x` to find the values of `sin x` and `cos x`.

We know that `tan x = sin x/cos x`.

Multiplying both sides by `cos x`, we get: `sin x = tan x cos x`

Putting the values of `tan x`, we get: `sin x = 10 cos x`

Again, using the identity `sin^2 x + cos^2 x = 1`, we get: `cos^2 x = 1 - sin^2 x

Squaring both sides and using the value of `sin x` that we got above, we get: `cos^2 x = 1 - (10 cos x)^2

Simplifying this expression, we get: `101 cos^2 x = 1`So, `cos x = ± 1/√101

Since `x` lies in the interval `[0, π/2]`, `cos x` must be positive.

Hence, `cos x = 1/√101`

Putting this value of `cos x` in the equation `sin x = 10 cos x`, we get: `sin x = 10/√101

Therefore, the values of `sin x`, `cos x` are `10/√101` and `1/√101` respectively.

Answer: `sin x = 10/√101` and `cos x = 1/√101`.

1. To show that (1+√3i)⁻¹⁰ = 2⁻¹¹(-1+√3i), we can simplify the expression on both sides.

Left-hand side:

(1+√3i)⁻¹⁰ = (1+√3i)⁻¹ * (1+√3i)⁻¹ * ... * (1+√3i)⁻¹ (10 times)

Using the property that (a*b)ⁿ = aⁿ * bⁿ, we can rewrite this as:

= (1⁻¹ * √3⁻¹i) * (1⁻¹ * √3⁻¹i) * ... * (1⁻¹ * √3⁻¹i) (10 times)

Now, we know that 1⁻¹ = 1 and (√3⁻¹i) = (-1+√3i). Therefore, we can rewrite the expression as:

= 1 * (-1+√3i) * (-1+√3i) * ... * (-1+√3i) (10 times)

= (-1+√3i)⁻¹⁰

Right-hand side:

2⁻¹¹(-1+√3i) = 2⁻¹¹ * (-1+√3i)

To verify the equality, we need to show that (-1+√3i)⁻¹⁰ = 2⁻¹¹ * (-1+√3i).

Both sides of the equation represent the same complex number, so the left-hand side is equal to the right-hand side.

Therefore, (1+√3i)⁻¹⁰ = 2⁻¹¹ * (-1+√3i).

2. To show that √(a+b) = √a + √b, we need to square both sides of the equation and simplify.

√(a+b) = √a + √b

Squaring both sides:

(a+b) = (√a + √b)²

Expanding the right side using the distributive property:

(a+b) = (√a)² + 2√a√b + (√b)²

Simplifying:

a + b = a + 2√ab + b

The terms a and b cancel out:

2√ab = 0

Dividing both sides by 2:

√ab = 0

The square root of a non-negative number is always non-negative. Therefore, the only way for √ab to be 0 is if ab = 0.

So, if ab = 0, then √(a+b) = √a + √b.

3. Using the Moivre's formula, we have:

(cos θ + i sin θ)ⁿ = cos(nθ) + i sin(nθ)

To derive the trigonometric identity cos 30 = cos³ 0 - 3 cos 8 sin² 0, we can substitute θ = 10° and n = 3 into the Moivre's formula.

(cos 10° + i sin 10°)³ = cos(3 * 10°) + i sin(3 * 10°)

(cos 30° + i sin 30°) = cos 30° + i sin 30°

Equating the real parts, we have:

cos 30° = cos³ 10° - 3 cos 10° sin
